  1. 6. Assessment of the integration of solar heat power into food drying processes

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Charalampos Psilopoulos; [2023]
    Nyckelord :Sustainable; sustainability; co2 reduction; feasibility; solar thermal; direct steam generation; drying; food industry; scope 1 emissions; sdg; sustainable development goals; spray drying; drum drying; powder; food; Technology and Engineering;

    Sammanfattning : The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit significant amounts of Greenhouse Gases (GHGs).

  3. 7. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Khalil Daloul; [2023]
    Nyckelord :Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Sammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER

  4. 8. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Malin Gelfgren; [2023]
    Nyckelord :;

    Sammanfattning : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. LÄS MER

  5. 9. Exploring backward stochastic differential equations and deep learning for high-dimensional partial differential equations and European option pricing

    Kandidat-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Jonathan Leung; [2023]
    Nyckelord :Backward Stochastic Differential Equations; Semilinear Parabolic Partial Differential Equations; Artificial Neural Networks; Nonlinear Option Pricing; Black-Scholes; Nonlinear Feynman-Kac; Euler-Maruyama;

    Sammanfattning : Many phenomena in our world can be described as differential equations in high dimensions. However, they are notoriously challenging to solve numerically due to the exponential growth in computational cost with increasing dimensions. LÄS MER

  7. 10. Analysis and Design of a Microgravity Drop Tower

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Tristan Edwards; [2023]
    Nyckelord :drop tower; microgravity;

    Sammanfattning : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. LÄS MER
